DeepReader – EPUB Reader & Language Learning

Hi, I’m the creator of DeepReader.

After learning three foreign languages, I discovered that reading books in their original language was one of the most effective ways to build fluency. But constantly switching between dictionary apps, flashcards, and reading tools made the process frustrating.

I created DeepReader to bring everything together in one place: a customizable EPUB reader, instant dictionary lookups, spaced-repetition flashcards, and offline neural text-to-speech.
